Deriving an Absolute Value in a Macro

by Allen Wyatt
(last updated September 16, 2020)

VBA provides a function to return the absolute value of an expression. For those who might not remember from math class, an absolute value is the positive equivalent of any expression. Thus, if a formula would normally result in a negative value, such as —27, the absolute value of that formula would result in the positive equivalent, or 27.

The syntax for the absolute value function is as follows:

x = Abs(y)

where x is the result and y is a value or an expression that evaluates to a value.
